Process and mechanism for determining the effective air temperature in at least one pneumatic tire of a vehicle
First Claim
1. A device for determining the effective air temperature in at least one pneumatic tire of a vehicle wheel comprising:
- a first temperature sensor means arranged at an interior side of a rim of the respective vehicle wheel for measuring the temperature at an interior side of the rim;
a second temperature sensor means in the immediate environment of a vehicle brake for measuring the temperature in the immediate environment of the vehicle brake;
a third temperature sensor means for measuring the ambient temperature of the vehicle; and
a computing unit connected to said three temperature sensor means for computing the effective air temperature in the respective pneumatic vehicle tire from the three measured temperatures.

Abstract
A process for determining the effective air temperature in at least one pneumatic tire of a vehicle sensor. In addition to the temperature in proximity of the interior side of the rim of the respective vehicle wheel, the temperature in the immediate environment of a vehicle brake disk or brake drum as well as the temperature in the immediate environment of the vehicle is sensed. From these measured temperature values, the effective air temperature in the respective pneumatic vehicle tire is then calculated. A mechanism for carrying out the process is disclosed. A formula for combining the sensor temperatures is disclosed. Lastly specific locations for the sensors are disclosed.
